The invention relates to a device that can be used to try electronic cigarette liquids, intended for the retail sale of electronic cigarettes, providing a system that allows the end client to try different electronic cigarettes without having to put together a complete assembly for each type of liquid, said device taking the form of a block provided internally with a set of clearomizers and vacuum pumps that convey the aroma into a single tube to the exterior. Alternatively, it can be assembled with a single vacuum pump or without any vacuum pump, using instead direction aspiration, or manual selection prior to the selected test or aspiration.

A method for in vitro simulation and evaluation of platelet adhesion in blood-contacting medical devices is disclosed, including the following steps: (1) using a glycerin aqueous solution with a mass percentage concentration of 40% in an extracorporeal circulation circuit to simulate a viscosity and hydrodynamic characteristics of blood, and adding fluorescent particles with a diameter of 3 m to 5 m to the solution to simulate platelets; (2) after the solution circulates in the circuit for a specified time period, removing flow passage components of a tested device, and observing the deposition of the fluorescent particles on a blood-contacting surface inside the device by naked eyes and photographs; and (3) using laser-induced fluorescence (LIF) technique to apply laser light on a device surface deposited with the fluorescent particles and in contact with blood, and using charge-coupled device (CCD) camera imaging to photograph the aggregation and adhesion of laser-induced fluorescent particles.

This document discusses, among other things, an apparatus comprising a pump configured to deliver a fluid, a wireless communication port, a controller, and a housing to enclose the apparatus. The controller is configured to communicate with a second device via the communication port using an open standard wireless communication protocol. The housing includes a mechanical coupling to slidably engage the second device which includes a second wireless communication port. Slidably engaging the second device positions the first and second communication ports opposite each other to allow communication via the first and second communication ports when slidably engaged.

The methods described herein provide improvements to the measurement of dose content uniformity of inhaler and nasal devices. The methods involve analyzing and measuring a spray pattern of an emitted spray from an inhaler or nasal device. The spray pattern may be used to determine the dose content uniformity of an inhaler or nasal device.

A method of analyzing a spray generated by a spray device for spraying pharmaceutical fluid, the method comprising the following steps: providing a spray head (1) of a spray device for spraying pharmaceutical fluid, said spray head (1) including a spray orifice (2); causing a test fluid to pass through said spray head (1) towards said spray orifice (2), said test fluid being air at a temperature that is different from ambient temperature; displaying, by strioscopy, the flow of test fluid leaving said spray orifice (2); and analyzing said display of the test-fluid flow so as to determine whether or not the test-fluid spray coming from said spray head complies with predetermined specifications.

An airway catheter (AEC) includes a catheter lube having proximal and distal tube end faces in fluid communication with a tube lumen. The distal lube end face and a portion of the tube wall collectively form a distal tube end region. A plurality of side holes extend laterally through the tube wall. An inflatable cuff is secured to the outer tube wall surface with an inner cuff volume in fluid communication with the tube lumen via the side holes. A resistor plug has proximal and distal plug end faces in fluid communication with a plug lumen and is defined laterally by a plug wall. The resistor plug is maintained within at least a portion of the tube lumen in the distal tube end region with an outer plug wall surface being at least partially in compressive contact with the inner tube wall surface.

In an embodiment, the present invention is an apparatus, configured to collect emitted sample dose from a drug delivery device, wherein the sample dose is an aerosol, wherein the apparatus comprises a collection assembly and a removable plunger.

An infusion device (1) for administering a medical fluid to a patient (P) comprises a pumping mechanism (11) for pumping a medical fluid through a delivery line (3), and a processor device (15) for controlling the pumping mechanism (11), during an infusion operation, to pump the medical fluid through the delivery line (3) in a downstream direction (F1). Herein, the processor device (15) is constituted to perform, prior to an infusion operation, a test function during which the processor device (15) controls the pumping mechanism (11) to pump the medical fluid through the delivery line (3) in an upstream direction (F2) opposite the downstream direction (F1). In this way an infusion device is provided that supports a user, in particular a nurse, to perform an infusion operation, in particular to set up the infusion device for performing the infusion operation.

A method for removing bodily fluid includes drawing bodily fluid that has accumulated in excess, converting the drawn fluid from bulk liquid form to aerosol form, and disposing of the aerosol via evaporation of liquid droplets and absorption and/or diffusion of vapor. Conversion from bulk liquid to aerosol may include collecting the bulk liquid fluid in a reservoir, conveying the bulk liquid bodily fluid to an atomizer, converting the bulk liquid fluid into an aerosol having ultrafine droplets, and ejecting the aerosol into a subcutaneous space for disposal via evaporation of liquid droplets and absorption and/or diffusion of vapors. The method may be performed with a subcutaneous atomizer that may be controlled locally or by an external transmitter for effecting a conversion and mist rate to keep pace with the accumulation of excess bodily fluid.

A syringe pump is disclosed that includes a body, a syringe seat, a syringe actuator, a memory, and one or more processors. The syringe seat is coupled to the body. The syringe actuator is configured to actuate a syringe secured within the syringe seat. The memory is configured to store a plurality of instructions. The one or more processors, in accordance with the plurality of instructions, is/are configured to: prime the syringe pump in a prime phase; determine if an occlusion exists during the prime phase using a first test; stop the prime phase; initiate fluid delivery into a patient; enter into a start-up phase; determine if an occlusion exists using a second test during the start-up phase; transition from the start-up phase into a steady-state phase; and determine if an occlusion exists during the steady-state phase using a third test.
